/* | |
First problem: referencing direct action in proxies/FormPanels | |
When using Ext.Direct with either Ext.data.proxy.Direct or Ext.form.Basic, you have to specify the function directly, so the function MUST previously be defined by calling Ext.direct.Manager.addProvider. This is a problem because normally the call to addProvider comes after the config evaluation. | |
For example | |
*/ | |
Ext.create('Ext.data.proxy.Direct', { | |
api: { | |
create: MyApp.mynamespace.MyAction.myMethod // This work only if Direct API is already defined | |
} | |
}); | |
/* | |
A solution for this problem can be to support specifying Direct methods by string, eg: | |
*/ | |
Ext.create('Ext.data.proxy.Direct', { | |
api: { | |
create: 'MyApp.mynamespace.MyAction.myMethod' // This is a string, that will be evaluated to a Direct function just before it will be called | |
} | |
}); | |
/* | |
At this point you can safely add Ext.direct.Manager.addProvider call in Ext.app.Application constructor, eg: | |
*/ | |
Ext.define('Ext.app.Application', { | |
constructor: function(config) { | |
if(config.directApi) { | |
Ext.syncRequire('Ext.direct.Manager'); | |
Ext.direct.Manager.addProvider(directApi); | |
} | |
// The rest ... | |
} | |
}); |
